CentOS更换yum源

一、备份

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

二、下载新的CentOS-Base.repo 到/etc/yum.repos.d/

 

CentOS 5

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo

 

CentOS 6

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

 

CentOS 7

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

三、以后运行yum makecache生成缓存

 

163 yum 源wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

注意，若是提示找不到路径，能够手动修改baseurl的地址
